Syntheses of dendrons for dendrimer applications are described using napthyl and urethane derivatives. The napthol, 1‐(3‐hydroxy‐6‐(methoxymethoxy)naphthalen‐1‐yl)ethan‐1‐one ( h ), was synthesized by employing Au‐catalyzed cyclization of the corresponding propargylic carboxylates. Polynapthol dendrons ( i , j , k , and l ) were prepared from substitution reactions of napthyl derivative h with alkyl/aryl halides under basic conditions. Branched polyurethane compounds ( q , r , and s ) were also prepared from addition reactions of 1,3,5‐tris(6‐isocyanteohexyl)‐1,3,5‐triazine‐2,4,6‐trione ( p ) with various alcohols under Lewis acidic conditions. The photophysical properties of the synthesized compounds h , k , and j were studied.
